【正文】 and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over. According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as highquality meats for each meal. After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym. In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing. 28.

D Astronauts on shorter shuttle missions(任務(wù) ) often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day’s work. This type of schedule is far too demanding for long missions on the International Space Station(ISS). ISS crew members usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can municate with family and friends by , Inter phone and through private video conferences. While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crew member put together a collection of family photos, massages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2020, the Inter became available on the ISS, giving astronauts the chance to do some ―web surfing‖ in their personal time. Besides relaxing with these more mon entertainments, astronauts can simply enjoy the experience of living in space. Many astronauts say that one of the most relaxing things to do in space is to look out of the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the pla several times each day, and every moment offers a new view of the Earth’s vast mass and oceans. 32. What does the word ―mimic‖in Paragraph 1 probably mean?
